Telegram webhooks with nginx reverse proxy

Make config file:

sudo nano /etc/nginx/sites-available/bot.conf

Then copy and paste bot.conf content and edit YOUR.DOMAIN strings. Now install Let's Encrypt on your server. For example in Debian you need to add jessie-backports and easily install it with apt-get:

sudo apt-get install -t jessie-backports letsencrypt

Then get cert for you domain:
